SPECIFICATION formingpart of Letters Patent N 0. 635,631, dated October 24, 1899.

Application filed August 2 1899.

To all whom it may concern:

Be it known that 1, ROBERT ZIMMERMANN, doctor of philosophy and chemist, a citizen of the Swiss Republic, and a resident of Brugg, canton of Argovie, Switzerland, have invented new and useful Improvements in Closing Devices for Receptacles Having Capillary Openings for the Transport, Storage, and Use of Volatile Liquids, of which the following is a clear and complete specification.

For several years past various devices have been invented having for their object to effect the hermetic closure of glass or metal receptacles for volatile liquids having one or more capillary openings. Thus screw and bayonetlike closures and covers with spring action have been used, also a closure consisting of a long caoutchouc band that was laid around theentire receptacle and in pressing upon the capillary opening was supposed to effect the closure thereof. This last-named system has, however, not been found practical, because it was necessary to provide at the end of the receptacle opposite the capillary opening a device for holding the band, which, however, did not afford the necessary security for holding it in position. In addition the application of such a long band was inconvenient for use, because, not being permanently connected to the receptacle, it required a certain amount of practice to properly place it over the opening again after use. This band device has, however, a decided advantage in that all use of metal and risk of formation of verdigris,such as frequently occurs with brass closing devices, is avoided.

My invention relates to a closing device which allows in a very simple and reliable manner to effect a hermetic closure of a cap semi to. 725,864, (No modeLl while Fig. 4 shows the form of receptacle shown at Fig. 2 with the caoutchouc band removed from the capillary opening.

The glass capillary nozzle a of the receptacle (whether it be formed in one with the receptacle, as would be the case if thiswere of glass, as shown, or whether the capillary nozzle be combined in any suitable manner with a metal receptacle) has at more or less short distance from the opening a knob-like swelling 1), which may either be hollow, as at Fig. 2, or be made solid, as in Fig. 3, so that there is no enlargement of the passage of the nozzle. This swelling has for its object to hold the ring-shaped caoutchouc band?) like the button and buttonhole of an article of dress, the band being for this purpose provided with an opening (not formed byasimple incision, as the band would then be liable to tear) which is passed over the swelling, so as to be retained behind it. The closure of the capillary opening is now effected in an exceedingly simple and quick manner by seizing the loop of the band and in stretching it placing it over the opening. When the receptacle is to be used, the opening is uncovered by simply drawing the loop of the band t'to one side, so as to remove it from the opening. The band thus remains attached to the receptacle both when this is in or out of use, being retained behind the swelling; but should it become defective it can readily be removed and replaced by another one.

What I claim is- A closing device for a receptacle with capillary opening for containing volatile liquids consisting of the combination of a ring-shaped caout-chouc band having a buttonhole-opening and a nozzle having a swelling or button at a short distance from its capillary opening the band being fitted with its buttonhole over the said swelling, and having its other part stretched over the capillary opening, substantially as described.

In witness whereof I have hereunto signed my name, this 12th day of July, 1899, in the presence of two subscribing witnesses.

ROBERT ZIMMERMANN.
